I have suffered for chronic pain, epilepsy & depression (which includes cutting) since I was injured at work. I am on Effexor (450 mg) & was seeing someone but he decided not to take Worker Comp anymore. I read something about Bi Polar & Uni Polar could you please explain what each is & can you develop Bi Polar when your older (I am 51 now) I have never been told I have it and my last Dr said he thought I didn't.
